This is the English version
The Google metadata for Mathias Sandorf is apparently all messed up. This is NOT the French original published by Hachette as it claims. Check the Read online and you'll see that it's the English translation published by Samson Low et al of London in 1889.
If you're looking for an English edition of volume 1, this is what you want.
